WRONG Im tired of explaining it to you. When using a small sensor, 24x36mm or less, there will be ZERO difference in field of view, depth of field, apparent magnification etc. etc. between a 645 400mm lens and a 35mm 400mm lens. PERIOD. This isnt theory, this is real. jco ---------------------------------------------------------------------------- J.C.

The in-camera crop of the smaller than nominal fullframe sensor yields on the memory card the same effect as cranking up the enlarger head to project just the cenrtal area of a regular negative. That cropped image is what the see and what they get. Again, DOF, resolution, etc are not part of my point - just that the end result on the media has a longer reach.
